Also keep in mind just because a given motorhome can tow 5,000 pounds, does not mean you should. We have a 28 ft class A with a 5,000 pound tow rating, along with 2 TOAD cars a 2,300 pound Toyota Yaris, and a 4,300 pound Jeep Cherokee, when towing the Yaris I have to keep my rear view camera on to know it is back there, with the Cherokee there is never any doubt, and it shaves a few miles per hour off my comfortable max driving speed.
On another topic, have you considered the logistics of flat towing a car while traveling solo? I personally have not yet towed a car while taking solo trips due to some of these logistics concerns, what to do if, etc. For example my wife and I just returned home from a 900 mile round trip to see the solar eclipse last week, on the third day of the trip as we were preparing to leave a campground while doing the brake and turn signal check on the TOAD car we found the right turn / brake light was not working. I spent about an hour trouble shooting, which was complicated by the fact whoever wired the tail lights on the Yaris did not use standard trailer wiring color codes. Since it was check out time, we had reservations for the next 3 nights, etc. my wife ended up driving the TOAD car 120 miles to the next campground, something I would not have been able to do if towing solo. Last October I took a circa 900 mile solo trip, and specifically choose to leave the TOAD cars behind due to such what if concerns.
